中文摘要：

从Drude色散理论和薄膜光学的基本方法出发，用理论公式对在线Low—E玻璃的透射谱线进行拟合，得到了Low—E玻璃功能层的光学常数。利用Burstein—Moss理论，计算得到了功能层的自由戡流子浓度；理论计算与实验结果的一致性表明，Drude理论不仅能很好地定量解释在线Low—E玻璃的光学特性，而且为在线Low—E玻璃光学常数的理论计算提供了一种切实可行的方法。

英文摘要：

Based on the Drude theory and basic method for thin film optics, the optical constants of functional coating of online Low-E glass are obtained by fitting the curve of measured transmission spectrum using theoretical formula. Meanwhile, the carrier concentration of functional coating is calculated in terms of Burstein-Moss theory. The unity of theoretical and experimental results has suggested that the Drude theory can not only explain the optical properties of online Low-E glass very well, but also provide a practical method for the calculation of optical constants of online Low-E glass.
